Widely known as one of the best Katsuura Tantanmen spots. Characterized by so much chili oil it forms layers in the red soup, with soft caramelized onions adding sweetness to the heat. Despite its hidden location up a slope, peak waits reach 1 hour. Tabelog 3.51/340 reviews. A son-operated branch exists in Tomisato City (2 locations total).
Yahoo Maps 3.82/35 reviews. Tabelog 3.51/340 reviews. Reviews note 'despite being up a slope there's still a line' and 'less spicy than the red soup looks, but packed with umami.' Often cited alongside Ezawa and Matsunoya as the top three Katsuura Tantanmen shops. January 2025 review confirms reopening.
